Product Overview: 

This premium shop grade pre-greased trailer hub and drum assembly kit is engineered to provide a comprehensive, time-saving replacement solution for heavy duty 7,000 lbs trailer braking axles. Built specifically for high capacity axles with an 8 on 6-1/2 inch wheel bolt center, this complete hub-drum assembly comes pre-packed with high quality automotive grease and features pre-installed inner and outer races within the precision-cast drum cavity. The kit includes an industry-standard 25580 inner bearing cone and a 14125A outer bearing cone to deliver a heavy duty friction reduction system. The integrated 2.25" grease seal ensures reliable lubricant retention while actively blocking external moisture and highway grime from entering the braking system. Optimized for direct compatibility with standard 7K trailer braking systems, this complete mechanical maintenance solution includes premium 1/2-20 inch wheel studs and standard 60-degree cone nuts alongside both standard and E-Z Lube compatible grease caps, a specialized rubber plug, a detailed instruction sheet, and essential spindle retention hardware such as a slotted nut, hex nut, retainer nut, D washer, and cotter pin. This pre-lubricated heavy duty assembly eliminates the mess and inconsistency of manual packing, extending spindle life and ensuring reliable braking and smooth towing across thousands of miles.
